[LLVMdev] open source multithreaded garbage collector suitable for LLVM applications?

[Chris Hanson]

Apple's autozone is a concurrent non-copying collector written in C++  
that should be adaptable to your needs. You could even take a look at  
clang to see how to generate code for it; autozone is the collector  
used by Objective-C garbage collection.

It's under an Apache license and downloadable from the Darwin open  
source repository. Google should point you to it.
